1.Introduction
Whether you are on the stage or in the studio, you often find that you need to connect an audio source to your mixing console, but you don’t have the appropriate connectors. For example, only few keyboards feature balanced outputs; guitars should not be connected directly to the console; and placing a microphone in front of an amp is not always an ideal solution, because the mic will pick up unwanted signals from other instruments, too. Low frequency signals (e.g. produced by a bass guitar) are particularly difficult to handle using these techniques.
“DI” is short for “Direct Injection”. A Direct Inject box allows you to use a
and possibly convert them to balanced signals before. As you can expect, the DI4000 offers you a reliable solution.
The following explanations will give you an introduction to the complex
By the way: there are two basic types of DI boxes, passive and active. Both can be connected to one of the console’s mic inputs. Passive DI boxes offer the advantage that they are less expensive than active models (less electronics, no power supply), however, their performance depends on the connected impedance. With a passive DI box connected, any impedance change on the console side will also modify the input impedance. The frequency response will always depend on the impedances connected. Any passive DI box will only perform properly with accurately specified impedances (high on the input side, low at the output), i.e. it will only work in standard situations.
